Let $V$ be a complex quasi-projective variety, we know from H. Whitney's and B Teissier works on stratifications of algebraic varieties that $V$ has an intrinsic stratification
$$X\_0\subset X\_2\subset\ldots\subset X\_{2n}$$
made out by complex quasi-projective smooth varieties that satisfy Whitney conditions $a$ and $b$.
This stratification induces a structure of topological stratified pseudomanifold on $V$ meaning in particular that any point $x\in X\_i$ has a conical chart, a stratified homeomorphism:
$$\phi:U\_x\rightarrow V\_x\times cL$$
where $L$ is a topological stratified pseudomanifold of dimension $2n-i-1$, $cL$ is the cone on $L$, $V\_x$ is an open neighbourhood of $x\in X\_i$ and $U\_x$ is an open neighbourhood of $x\in V$. 


A priori $\phi$ is just a stratified homeomorphism (for a proof one can look at N. A'Campo survey in Armand Borel et al. lecture notes "Intersection cohomology" chapter IV Birkhauser), but we can ask wether if this intrinsic stratification gives us a Piecewise Linear stratification.


In 1984 A'Campo explains that this question is open for analytic spaces, I was wondering if an answer is known in the case of complex algebraic varieties. 



Stratification of complex algebraic varieties
So i turned my comment into an answer after reading [1] again.


A Whitney stratification, i.e. a stratification satisfying Whitney's condition b (and so automaticly a), induces a triangulation compatible with the stratification. Especially this gives a PL-stratification compatible with the Whitney stratification:


See the comment: " By [Gor78], a Whitney stratified pseudomanifold X can be triangulated so that the Whitney stratification defines a PL stratification of X." in [2]
